SPECIFICATION forming part of Letters Patent N 0. 397,785, dated February 12, 1889. Application filed December 22, 1887. Serial No. 258,761. (No model.)

To all whom it may concern:

Be it known that I, JOHN M. DAVIS of Marathon, in the county of Cortland, in the State of New York, have invented new and useful Improvements in Railroad Cross -Ties, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention consists in an improved c011- struction of a metallic cross-tie for railroads and means for securing the rails thereto, which afford a secure and permanent support for the rail and permit a ready removal of the rail when required for repairs or renewal.

The invention is fully illustrated in the annexed drawings, in which Figure l is a side elevation of the crosstie wit-h the rails mounted thereon, a portion of one of the side ribs being broken away to better illustrate the attachment of the rail-holding jaws. Fig. 2 is a top plan view of one of the end portions of the tie. Fig. 3 is a vertical trans"'e rse section on line a; .r, Fig. 2; and Fig. t is a top plan view of a modification of my invention.

Similar letters of reference indicate corresponding parts. I

T represents the cross-tie, on which the rail R is mounted. Said tie is composed of the lmse-plate f, from which rise longitudinal side ribs, a a, and central rib, a, extending from end to end of the tie and preferably formed crowning to impart increased strength to the same. Transverse ribs g g unite the longitudinal ribs and brace the same laterally. The

central longitudinal rib, a, has integral with it jaws Z) b,which grip the bases of the rails R R at one side, preferably at the outer side of the rail. At the opposite orinncr side of each rail I detachably connect to the aforesaid central rib, a, a jaw, b, which grips the base of the rail at said side. This jaw rides on the aforesaid rib and is provided with downwardly-extending flanges c c, embracing between them the rib. A bolt, d, passes transversely through the flanges c c'and ribs a a a and thereby fastens the jaw b to the rib. The jaw is further supported by shoulders e c, rigidly attached to the rib a at the heel of the jaw. Upon the ribs a are also formed projections or shoulders I)", which oppose strain or movement of the rail toward the center of the track and thereby relieve the bolt cl of such strain;

At the joints of the rails I employ a tie having the jaws b I) attached to the side ribs, a a, as shown in Fig. 4 of the drawings, thereby fastening the adjacent end of the rails without the aid of the usual fish-plates placed across the joints of the rails, and said fishplates may therefore be dispensed with. Underneath the rails R R, I provide the tie T with enlarged hearings on the road-bed by widening the end portions, 7 f, of the baseplate f and brace the same by vertical ribs h It on the exterior of the longitudinal ribs a 0;.

It will be observed that my improved tie affords by the ribs a a a three substantial bearings for each rail, and the rail can be readily removed, when required for repairs or renewal, by simply removing the bolt (1 and raising the jaw b from the rib a. The side and end ribs of the tie I perforate, as shown at i 1', for the purpose of allowing the water to escape from the troughs formed by the said ribs.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In combination with the tie T, formed with the longitudinal ribs a co, the jaws b 1), formed integral with the central rib, a, at one side of the rails, the jaws b b, detachably connected to and riding on the central rib at the opposite side of the rails and provided with the downwardly-extending flanges c at opposite sides of the rib, the bolts cl d, passing transversely through said flanges and ribs, and the shoulders e e on the central rib at theheels of the jaws b b, and shoulders b" upon ribs a, substantially as describedand shown.

2. The tie T, composed of the base-plate f, formed with the widened end portions, f f, longitudinal side ribs, a a, rising from the base-plate, transverse ribs 9 g between the ribs a a, and braces h h 011 the end portions f f outside of the longitudinal ribs, all rigidly united, substantially as described and shown.

3. The improved tie T, composed of the baseplate f,formed with the widened end portions,
